A diamond's clarity grade influences both its beauty and price. VS1 , VS2 and SI are among the most common clarity levels used in engagement rings, but what do they mean and how do they compare?
### What does clarity mean?
Clarity refers to the presence of internal inclusions and surface blemishes in a diamond. The fewer imperfections, the higher the clarity grade. The Gemological Institute of America (GIA) clarity scale ranks stones from Flawless (no inclusions) down to Included.
### VS1 vs VS2 vs SI – How they compare
- VS1 (Very Slightly Included 1): Minor inclusions that are difficult to see even under 10× magnification. Generally eye‑clean to the naked eye.
- VS2 (Very Slightly Included 2) : Slightly more inclusions than VS1 but still eye‑clean in most stones. Offers a good balance of quality and value.
- SI (Slightly Included) : Inclusions are noticeable under 10× magnification and sometimes visible to the naked eye, depending on stone size and cut. More affordable than VS grades.
### Which clarity is right for you?
- Budget : SI stones are more budget‑friendly but may show inclusions. VS2 offers mid‑range clarity at a moderate price. VS1 is premium quality with a higher price.
- Carat and cut : Larger stones show inclusions more easily. Consider higher clarity for diamonds over 1.5 ct. Brilliant cuts hide inclusions better than step cuts (e.g., emerald cut).
- Personal preference : Some buyers prefer a flawless look while others prioritise size over clarity.

### FAQs
What is an eye‑clean diamond?
An eye‑clean diamond has inclusions that aren’t visible to the naked eye. VS2 and VS1 grades are typically eye‑clean.
Can inclusions affect durability?
Rarely. Only extreme inclusions near the surface or along a cleavage plane risk breakage.
Do lab‑grown diamonds have clarity grades?
Yes. Lab‑grown diamonds are graded using the same GIA clarity scale.
